Specification of Letters Patent.

Patented Aug. 1 1915.

To aZZ whom it may concern: y

Be it knownthat we, .HARALD Tnrcevn PARMFELT, a subjectof the King of Sweden, and resident of Sodra Esplanaden 8, Lund, in the Kingdom of Sweden, and FR noLr ALLBERT TULLBERG, a subject of the King of Sweden, and resident of Alnarp, llkarpfln the Kingdom of Sweden, have inventedcerta-in new and useful Improvements in-Harvesters, of which the following is a specification, reference being had therein to the accompanying drawings.

Harvesters hitherto known cut off the straws immediately above the ground, gather the'same and sometimes bind the same in sheaves, whichare placed behind the machine or at the side of the same. This invention relates toa harvester, which'differs from harvesters before known by-the fact-that the straws are cut ofi at'two points viz. at the roots t. e.-near the ground, and immediately be1ow-the cars, so that the ears are separated from the straws. The ears thus cut off are gathered in a suitable receptacle, while the straws are placed behind the machine or at the side of thesame by. a suitable conveyer.

A form of the invention is shown inthe accompanying drawings.

Figure 1 is a side view and Fig. 2 a ,plan view of the fore part of the harvester. Fig. 3 is a front view of the-harvester. 4 is a section on the line A -to Bof Fig. 3. Figs. 5 and 6 are a side view 1and a--plan view respectively of a detail. Fig. 7 shows in a plan view and on of the harvester.

The harvester comprises a frame 2, carried by wheels 1. In the lower, fore part of the said frame the cutting kniwes 3. are provided fixed to a rod extending transversely of the motion direction of the machine aid e low. The said knives out off the straws ata shortdistance above the ground. In ,the top part of the frame 2 a comb 4 is provided, consisting of a plurality of parallel, narrow rods, extending, forward and, if {necessary downward. -Dur1ng the operation. of the at w l fa ,injt e i uriee s a greater scalea part v higher level 131 c wheels .of ,th

direction indicated and the same into the spaces by the e r-e in i l between the rods of the comb a, with the ears located above the rods.

Atthe rear end of the comb ia second reciprocated rodwith knives Sis provided lge 1 a level than the knives 3 and somewhat behind the samewithrelation to the moving direction of the harvester. Ilhe knives 8 cut off the straws immediately below the comb 6. immediately b low. the ears, so that the how ee ted. ehi the -,comb,; while the straws fall upon a slantd upon an endless -convey er ,10, whichmoves the same backward to a second endless conyeyer 1,1, which is moved ran rsely e h n -Ch n e tran r the straws to one of the slides of the same. At the rear edge of the conveyer last mentioned an endless chain. 12. is provide dliavins p oje ti ns 3.0 t l k and m ve i the same direction as the conveyer.

" The rre k f whee upp t n t e e i 12 a th side of th mac in epnee toe the e verye eef th sam ,i ile e e e e t a the preeh t Wheel ocated at the side last mentioned, so that the top part ofthe chain has a slanting position.

Thesaid chain 12 together with'a wall 12*,

. a e leeete a h re d of t ee Y l1 .and having anoblique top edge .corresponding tofthe slanting position of the chain 12, prevent the straws from falling down behind the machine, whilethe chain assists in moving the straws toward the delivery side of the machine.

The means transmitting the motion fro harvester to the operating ribs engage the straws and move the machine.

parts of the same may be of any suitable construction. In the form shown in the drawings the greatest wheel 1 is provided at its inner side with teeth 15 meshing with a toothed wheel 16, which is fixed to a transverse shaft 17, journaled in the frame 2. From the said shaft 17 motion is transmitted to the operating parts of the machine. To the shaft 17 a bevel-wheel 1.8 is fixed, meshing with a bevel-wheel 19, which is fixed to a shaft 20 forming a right angle with the shaft 17. The said shaft 20 rotates by means of a gearing 21 a shaft 22, provided at its fore end with a crank disk 23, which reciprocates the rod carrying the knives 3 by means of a pitman 24. To the inner end of the shaft 17 a bevel-wheel 25 is fixed, meshing with a double bevel-wheel 26 fixed to a vertical shaft 27. The said bevel-wheel 26 meshes with a bevel-wheel 28, fixed to the driving shaft 29 of the endless conveyer 10, and with a bevel-wheel 30 fixed to a backward extending shaft 31, which by means of a gearing 32 rotates one of the shafts 33 of the endless conveyer 11. The same shaft 33 also actuates the endless chain 12.

At the bottom of the box 9 a screw conveyer 34 or any other suitable conveyer is provided which moves the cut off ears to a delivery funnel 34 located at the side of the The said screw 34 is rotated by means of a chain 38 and sprocket wheels by a top shaft 39, which is rotated by a bevel gear 35. One of the wheels of the said gearing 35 is fixed to a shaft 36, which is rotated by the shaft 27 by means of a gearing not shown and located in a latch gear casing 37. The shaft 39 rotates by means of a bevel gear 40 a shaft 41, provided at its fore end with a crank disk 42, which reciprocates the rod carrying the knives 8 by means of a pitman 44. The rear wheels 5 of the feed device 6, 7 are fixed to a shaft 45, which is rotated by the gearing in the latch gear casing 37.

In order that the harvester may be adapted to straws of different heights the rod carrying the knives 8, the box 9, the funnel 34*, the feed device 6, 7, the comb 4, the latch gear casing 37 and the gearings 35, 40 are as a whole adjustable to different levels on the uprights 2 of the frame. In order to facilitate the said adjustment the center wheel of the latch gear casing is movable longitudinally of the shaft 27 but can not rotate on the same. This may be efiected for instance by the shaft 27 being square or provided with a longitudinal key engaging a recess provided in the hub of the said center wheel.

The mode of operation of the harvester is easily understood from the above description. The straws are caught by the comb 4 and are then cut off by the knives 3, so that the straws will hang on the ears, supported by the rods of the said comb 4. Owing to the forward movement of the machine in the crop and by means of the feed device 6, 7 the straws, cut off at their lower ends are moved up the comb until the ears are cut from the straws by the top knives 8. The advantage of gathering in the ears separately is obvious. For instance they may easily be dried in kilns. The straws may be gathered afterward.

Having now described our invention, what we claim as new and desire to secure by Letters Patent is:

1. In a harvester the combination of knives located in position to cut the straws near the ground, a comb located above the knives in position to receive the straws below their ears and hold the straws suspended and other knives located at the rear portion of the comb in position to sever the ears from the straws.

2. In a harvester the combination of knives locatedin position to cut the straws near the ground, a comb located above the knives in position to receive the straws below their ears and hold the straws suspended, a feed device, for assisting in moving the straws into the said comb, and other knives located at the rear portion of the comb in position to sever the ears from the straws.

3. In a harvester the combination of knives located in position to cut the straws near the ground, a comb located above the knives in position to receive the straws below their ears and hold the straws suspended, other knives located at the rear portion of the comb in position to sever the ears from the straws, a conveyer for moving backwardly the straws from which the ears have been severed, and a conveyer for moving the said straws to one of the sides of the harvester.

4. In a harvester the combination of knives located in position to cut the straws near the ground, a comb located above the knives in position to receive the straws below their ears and hold the straws suspended, other knives located at the rear portion of the comb in position to sever the cars from the straws, a box located behind the said comb, into which the ears may fall, and a conveyer located at the bottom of the said box for moving the ears to one side of the harvester.
